Camera board • Re: Help! Trouble Synchronising Global Shutter Camera (IMX296) with Pi 5

I suggest you:

First:
1) verify you're starting the camera w/o the MAS soldered first (master). Then wait 2 seconds min. and start the slave/sink camera (MAS soldered).

Second if needed:
2) double check the connections - the breadboard and lack of soldered connections could contribute to miscommunication

The rpi5 works with with stereo GS cameras, refer to my post requesting feedback. However, some crucial features are broken including circular buffers and segmented recording.

Code:

echo 1 > /sys/module/imx296/parameters/trigger_mode

Code:

Or add "imx296.trigger_mode=1" to /boot/firmware/cmdline.txt
Or create a file /etc/modprobe.d/options_imx296.conf with the contents

Code:

imx296 trigger_mode=1

from picamera2 import Picamera2import timepicam2left = Picamera2(0)picam2right = Picamera2(1)left_config = picam2left.create_video_configuration({"format":"RGB888", "size":(740,320) },raw=None)right_config = picam2right.create_video_configuration({"format":"RGB888", "size":(740,320) },raw=None)picam2left.configure(left_config)picam2right.configure(right_config)picam2left.start()time.sleep(2)picam2right.start()left_img = picam2left.capture_array()right_img = picam2right.capture_array()t1 = picam2left.capture_metadata()['SensorTimestamp']t2 = picam2right.capture_metadata()['SensorTimestamp']print(t1 - t2)picam2right.close()picam2left.close()
